I've just upgraded to HTTP/2 for this website — not that you'll notice particularly. There's probably some speed improvements, but this is intentionally a website lite, so these will be small.
Test it (or any other website for that matter) by using nghttp client.
You can find appropriate nghttp packages for Debian and for Ubuntu. Other distributions are available.~$ nghttp -vn https://www.mgn.org.uk/
